The Camp Nou side are keen to add some fresh blood to their squad this summer and intend to hold on to current head coach Tito Vilanova

Barcelona vice-president Josep Bartomeu has revealed that the Catalans intend to sign four or five new players in the summer transfer window.

The Primera Division leaders have been linked with players such as Borussia Dortmund defender Mats Hummels and Santos forward Neymar in the past few months, but Bartomeu has stressed that they have not reached an agreement with the latter just yet.

“We’ll make four or five signings in the summer. We need to shake up the squad. We’ve also got players from the B team,” Barca’s vice-president told Catalunya Radio.

“We haven’t signed Neymar. He’s a player we are interested in, we’ve said that before, and we’ll see what happens when the season finishes.”

Bartomeu also had his say on the future of Tito Vilanova and insisted that the 44-year-old will continue to be Barcelona’s head coach.

“Tito will continue next year.”

Vilanova replaced Pep Guardiola as Barca coach at the start of the 2012-13 campaign and guided them to their best-ever start in La Liga.

The Camp Nou side currently sit atop of the league table, holding a 13-point lead over second-placed Real Madrid.

The Brazil international hopes the club’s talisman will remain in the French capital as rumours of a summer exit gather pace

Thiago Silva has urged Zlatan Ibrahimovic to stay at Paris Saint-Germain this summer amid interest from Juventus and Manchester City.

The Serie A champions are closely monitoring the Sweden international’s situation in the French capital in their search for a top striker, while City see the Sweden international as a good alternative in case they fail to land Napoli star Edinson Cavani.

However, his team-mate Thiago Silva has revealed his desperation for the club’s talisman to remain at Parc des Princes and see their adventure through to its conclusion after both joined from PSG last summer.

“I hope Zlatan will stay at PSG. He can help the team and the club grow. I really want him to stay put,” Thiago Silva told Le 10 Sport.

“I have not yet had the opportunity to talk to him about whether he has already made a decision on his future.

“He’s a normal guy who always wants to win. He gets angry when things don’t go well. Sometimes this is a good thing and sometimes it isn’t. I see him as a positive guy, though, who gives strength to the team.”

The 31-year-old has a contract with the Ligue 1 leaders until June 2015.

The striker’s representative has brought the club down to earth with a bang after claiming the player will definitely be leaving in the summer

Robert Lewandowski’s agent Maik Barthel has stunned Borussia Dortmund by revealing the striker has agreed terms with another club – less than 24 hours after scoring four goals in BVB’s 4-1 win over Real Madrid.

The likes of Bayern Munich, Juventus, Manchester United and Manchester City are all believed to be keen on luring the Poland international away from Signal Iduna Park this summer.

BVB have so far stressed that they have no intention of selling their star attacker, though a transfer now seems inevitable following comments made by the player’s representative on the the back of one of the finest nights in the club’s history.

“We have reached an agreement with another club and intend to switch clubs this summer,” Barthel was quoted as saying by Sport Bild.

“All of Borussia Dortmund’s demands will be met.”

Lewandowski’s agent then went on to stress that BVB have promised the striker that he will be allowed to leave under the right conditions and expects Jurgen Klopp’s side to honour their promise.

“There is an interesting offer for Robert that meets Dortmund’s criteria and satisfies Robert’s demands. BVB have assured us that Robert will be allowed to leave under these circumstances. It’s now up to the clubs to sort it out.”

The 24-year-old has a contract until the summer of 2014, with his exit another potential hammer blow for Dortmund following the news Mario Gotze will join rivals Bayern Munich in the summer.

The Italy international previously appeared to be on his way to the Serie A champions, but has now caught the attention of the San Siro side as well

EXCLUSIVEBy Romeo Agresti

Inter have joined Juventus in the race for Bologna star Alessandro Diamanti Goal.com understands.

The Italy international appeared destined to join the Scudetto holders this summer as both sides had been in talks over the attacker for a number of weeks.

Nevertheless, Inter are keen to hijack the Turin giants’ move for Diamanti as they bid to bolster their forward line at the end of a season of great inconsistency.

The San Siro side have yet to make an official offer for the former West Ham forward, but plan to contact Bologna in the upcoming days to discuss a potential summer transfer.

Diamanti has been linked with a move away from his current employers on a regular basis since joining the Rossoblu in the summer of 2011 and it is believed the player is determined to make the step up.

The 29-year-old will not be available on the cheap, though, as he has a contract with Bologna until the summer of 2017.
